autofs doesn't work if containers are used.  The first patch fixes this.

Both the patches replace pid_t with a refcounted struct pid object,
which has better lifetime properties: you don't know whether a pid_t is
valid, because pid numbers are reused, while pid objects remain valid
until there are no more references to them.
